Pharmaceutical Residues in Wastewater Treatment Plants and Surface Waters in Bangkok
(American Society of Civil Engineers, 2012)Pharmaceutical residues are increasingly found in wastewater treatment plant effluents and river water in very low concentrations at nanograms per liter levels in many countries. In this study, samples were collected from ... -
Kinetic Analysis of Thermal Degradation of Polypropylene Using a Modified Gompertz Model
(American Society of Civil Engineers, 2012)A new method, called modified Gompertz model, was proposed to interpret solid state decomposition. To verify the validity of this new model, the thermal degradation of polypropylene (PP) was performed and the results of ... -
Use of White Rot Fungus <i>Pleurotus ostreatus</i> as a Biodegradator of Naphthalene in Contaminated Soil
(American Society of Civil Engineers, 2012)The capacity of white rot fungus, -
Removal of 17β-Estradiol from Groundwater Using Nanoporous Molecularly Imprinted Polymer Adsorbent
(American Society of Civil Engineers, 2012)A polymer adsorbent specific for -
Capacity of Straw for Repeated Binding of Crude Oil from Salt Water and Its Effect on Biodegradation
(American Society of Civil Engineers, 2012)Using mass balance studies, we show that wheat straw readily bound several times its own weight in crude oil floating on salt water, the straw was reusable following repeated extractions of the oil with diesel, and its ... -
Optimal Groundwater Remediation by Pump and Treat Using FEM- and EGA-Based Simulation-Optimization Model
(American Society of Civil Engineers, 2012)Groundwater contamination is one of the most serious environmental problems in many parts of the world. For remediation of dissolved phase contaminants in groundwater, a pump-and-treat method is found to be a successful ... -
Posttreatment of UASB Effluents of Tapioca Starch Wastewater Using Downflow Hanging Sponge System
(American Society of Civil Engineers, 2012)This study is aimed at a performance evaluation of downflow hanging sponge (DHS) systems using mixed fungal and bacterial cultures for posttreatment of upflow anaerobic sludge blanket (UASB) effluents of tapioca starch ... -
PM10 and Heavy Metals in Suburban and Rural Atmospheric Environments of Northern India
(American Society of Civil Engineers, 2012)This study assesses the ambient air concentration of -
Virus Transport through Unsaturated Zone: Analysis and Parameter Identification
(American Society of Civil Engineers, 2012)This paper presents numerical and parameter estimation models for the analysis of virus transport and the identification of transport parameters in the unsaturated zone. The numerical model couples a mass conservative fully ... -
Toxicity Characteristics of Drilling Mud and Its Effect on Aquatic Fish Populations
(American Society of Civil Engineers, 2012)Toxicity tests are important for assessing the effects of complex chemical mixtures, such as waste drilling mud, on aquatic ecosystems. When waste drilling mud is released into the marine environment, strong ocean currents ... -
Coupled Reactive Transport Model for Heat and Density Driven Flow in CO2 Storage in Saline Aquifers
(American Society of Civil Engineers, 2011)In this paper, a novel reactive diffusion-convection transport model is proposed to investigate the flow during different -
Polycyclic Aromatic Hydrocarbon Emissions and Mutagenicity Assessment of Exhaust from a Diesel Generator
(American Society of Civil Engineers, 2012)Diesel fuel and diesel exhaust are known to be highly mutagenic partly because of the presence of polyaromatic hydrocarbons (PAHs) and their derivatives. The present study investigated the PAHs content in the diesel fuel ... -
Modeling of Cadmium Removal from Domestic Wastewater in Constructed Wetlands Using STELLA Simulation Program
(American Society of Civil Engineers, 2011)A mathematical model was developed to simulate cadmium removal from wastewater in free water surface (FWS) and subsurface flow (SF) constructed wetlands using STELLA simulation program. The model simulated the accumulation ... -
Sand Replacement Method for Determination of Shrinkage Limit of Fine-Grained Soils
(American Society of Civil Engineers, 2011)Mercury is one of the many hazardous substances that has been recognized and banned by many natural codes of practice and governments. Because many laboratory works in research and practice require the use of mercury, safe ... -
Bioremediation of Mixed Wastes (BTEX, TPH, TCE, and <i>cis</i>-DCE) Contaminated Water
(American Society of Civil Engineers, 2011)Together with industrialization, more sites have become contaminated with mixed wastes of organics. Contamination of groundwater with benzene, toluene, ethylbenzene, and three isomers of xylene (BTEX) and chlorinated ... -
Complex Risks from Old Urban Waste Landfills: Sustainability Perspective from Iasi, Romania
(American Society of Civil Engineers, 2012)Landfills continue to represent the most frequent managerial practice for municipal solid wastes and an increasing and complex problem globally. In certain countries, a transition to an open society and free market is ... -
Identification of Geologic Fault Network Geometry by Using a Grid-Based Ensemble Kalman Filter
(American Society of Civil Engineers, 2011)Discrete geologic features such as faults and highly permeable embedded channels can significantly affect subsurface flow and transport characteristics. Therefore, they must be properly identified, parameterized, and ... -
Pilot-Scale Simulation of Landfill Bioreactor and Controlled Dumping of Fresh and Partially Stabilized Municipal Solid Waste in a Tropical Developing Country
